GCRA - Generic Cell Rate Algorithm

Generic Cell Rate Algorithm is used to assess conformance of data entering the ATM (Asynchronous Transfer Mode) network at the UNI (User to Network Interface). The input of ATM cells is based on a QoS (Quality of Service) contract agreed between the customer and the network provider; the GCRA ensures this contract is adhered to by traffic shaping. If the flow does not conform to the agreed contract, the ATM switch may drop the non conforming cells.
